Frequent urination, Excessive thirst, Extreme hunger, Unusual weight loss, Increased fatigue, Irritability and blurry vision are some other symptoms of diabetes
I would suggest if you recognize one or more of these symptoms to take her to the doctor and request a Fasting Plasma Glucose Test or an Oral Glucose Tolerance Test. Those tests will give you a real answer and you won't just worry if she does have diabetes.
Always have your baby checked by a physician even if you can not afford it. Their life is in your hands do not delay. God Bless You!
